An extension of the XPane interface that adds support for
a) showing and hiding the windows that internally belong to the pane and
b) setting the accessibility object.
This is typically an optional interface.
Hide or show the pane. If there is more than one window used to
implement the pane then it is left to the implementation if one,
some, or all windows are hidden or shown as long as the pane becomes
hidden or visible.
Set the accessibility object for the pane. When there is more than
one window used to implement the pane then the given accessibility
object is usually set at the topmost window. However, the details
are implementation dependent.
